This July 2006 concert, performed in Venice's Gran Teatro La Fenice, is Keith Jarrett's seventh recording of the shorter solo-piano improvisations he's explored since the early 2000s, after chronic fatigue syndrome robbed him of the stamina needed to improvise for unbroken stretches of nearly an hour. Despite their many high points, none of its six predecessorsTokyo Solo, Radiance, Carnegie Hall, Testament, Rio, Creationmatched the cumulative power and depth of his best long-form improvisations: Köln, Sun Bear, Bregenz München, Paris. This one does.
